Subject: [dpdk-dev] [PATCH] net/ixgbe: fix hash handle leak
Date: Tue, 31 Aug 2021 21:24:07 +0800	[thread overview]
Message-ID: <20210831132407.7481-1-chenqiming_huawei@163.com> (raw)

In the ixgbe_fdir_filter_init and ixgbe_l2_tn_filter_init functions, after
the hash handle is created, the handle is not released in subsequent
abnormal branches.
